WebJun 8, 2024 · Crystal structures. Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), hexagonal close packed (hcp), or cubic close packed (ccp, also called face centered cubic, fcc). In all three structures the coordination number of the metal atoms (i.e., the number of equidistant nearest … WebThere are two types of voids involved in hexagonal close packing (HCP), namely octahedral voids and tetrahedral voids. We know that in a lattice, there are twice as many tetrahedral voids as there are close-packed particles. While the number of octahedral voids produced is the same as the number of tightly packed particles. WebHexagonal close packed (hcp) is one of the two simple types of atomic packing with the highest density, the other being the face-centered cubic (fcc).
